Turbulence
</dt>
A state of fluid flow in which the
instantaneous velocities exhibit irregular and apparently random fluctuations
so that in practice only statistical properties can be recognized and
subjected to analysis. Compare laminar
flow.
</dd>
These fluctuations often constitute major deformations of the flow and
are capable of transporting momentum, energy, and suspended matter at rates
far in excess of the rate of transport by the molecular processes of diffusion
and conduction in a nonturbulent or laminar flow. [[/a>|/a>
